Re: DHCP server ?

Oh, yeah. My mistake. I used static IPs in the end.. Ooops. If you really
want MAC support in PXELINUX (which is probably yur easiest option), you
could pay the guy that wrote/writes it to put it in...

Otherwise, become friendly with your local guys that think they are God
(your admins, or whoever does the DHCP)
